CHIP. CONVEYER I Filed Nov. 5, 1937 M 2. WWW, F11:y. 6 Q

Patented Nov. 8, 1938 UNITED STATES PATENT OFFIC 3 Claims.

This invention relates to wagons or other conveyers of the type particularly intended for use in factories for conveying oil soaked oil chips, or the like, from one place to another, as, for instance,

v from the machine where produced to a dumping point.

An object of the invention is the provision of a conveyer of this character into which oil soaked chips may be deposited and which is adapted to separate, to a considerable extent, the

oil from the chips and to permit separate dumping thereof.

Another object of the invention is the provision in a device of this character of a door adapted to 1'! be pivotally swung outwardly and downwardly from closed position to be used as an inclined runway over which a wheelbarrow, or the like, containing chips collected from different machines, may be wheeled into the device for dump- 20 ing therein, and also adapted, when released for such purpose, to swing outward at its lower end portion to permit dumping of the chip contents when the front end of the device is raised.

Further objects and advantages of. the inven- 25 tion will be apparent from the following detailed description thereof, and from the accompanying drawing, in which- Figure 1 is a top plan View of a wagon type chip conveyer embodying the invention, with the 30., door at its rear end lowered in runway position; Fig. 2 is a side elevation thereof with door partly raised; Fig. 3 is a rear end view thereof, with the door in closed position; Fig. 4 is an enlarged fragmentary sectional view on the line 4-4 in Fig. 1,

35 with parts broken away; Fig. 5 is a side elevation of the device raised in dumping position, with the lower end portion of the door swinging outwardly, and with parts broken away; Fig. 6 is a section on the line 6-45 in Fig. 2, with parts 40 broken away; Fig. '7 is a section on the line 1-1 in Fig. 4, and Fig. 8 is a fragmentary sectional detail of. the latch member in relation to the wagon side.

Referring to the drawing, l designates What, in

45 the present instance, may be termed a wagon box, being supported by a pair of rear wheels 2 mounted on opposite ends of an axle 3 and supported at its forward end by casters 4 attached to a cross bracket member 5 projecting forwardly 50. from the front end of the box adj acent to its lower edge. The box I is preferably of rectangular form having a front end 6, opposite sides I and a rear open end adapted to be closed by a gate 8. The box also has the bottom l0 and a floor ll,

55 forming a false bottom, spaced thereabove and cooperating therewith to form a. bottom chamber l2 for'receiving oil draining from chips placed in the box over said floor.

The box is preferably of metal construction having, in the present instance, a frame of angle iron, with sheet metal mounted thereon, to close the sides, front end, and bottom. The false bottom ii is mounted on cross frame members it and comprises, in the present instance, a stationary part M at the rear end of. the floor and a pair of doors extending from said part M to the front end of the box and hinged at their outer side edges at Hi to adapt them to be opened upwardly and outwardly to facilitate access to the chamber l2. Each door has a handle I! to facilitate raising and fits sufficiently free within the box and over the supports it to permit drainage of oil therearound into the chamber it from the upper chip compartment of the box, or it may be'perforated or made of foraminous form for such purpose.

The gate 8 preferably comprises sheet metal mounted on angle iron strips and is provided at its bottom edge with a cross bar forming opposite end trunnions for seating in notches 2! in the top edges of bracket plates 22 secured to and projecting rearwardly from each side of the box at its lower rear end portion. The gate is provided near its top edge with a cross bar 23 forming end trunnions at the side edges of the gate which are adapted, when the gate is in upright position, to rest in the top notches of latch members 24 pivotally attached to and projecting rearwardly from the respective sides of the box near its top edges.

The latch members 24 are pivoted at their forward ends to the respective sides of the box and project rearwardly therefrom through guide slots 25 in the rear frame uprights 26 (Fig. 8) and are notched at the rear of said uprights, in their top edges, as at 21, to receive the ends of the cross bar 23. Each latch member 24 is connected by a link 30 to a rocker-arm 3| rising from the respective end of a cross shaft 32 mounted in the rear end portion of the box I below the floor II, and one or both of the arms 3! may be extended to form a control lever handle 33, which extends upward to convenient operating posi tion. A spring pressed plunger 34 is attached to each side of the box I and acts against the respective rocker-arm 3| to normally prevent a movement of the rocker-arms which will lower the latch members from notched engagement with the cross bar 23 when the cross bar 2!] is seated in the notches 2|. The rocker-arms 3| may, however, by the application of. forward pressure on either lever 33, be moved forward a distance against the tension of the spring pressed plungers 34 to effect a lowering of the latch members 24 and their consequent release from the cross bar 23 of the gate. This permits the gate to swing forward and downward about the cross bar 20 as an axis to rearwardly declining runway position. When the lever 33 is moved rearward from the normal position shown in Fig. 2, the latch arms 24 are raised, thus raising the gate 8 therewith and releasing the cross bar 29 from engagement with the notches 2|, thereby permitting the lower end portion of the gate to swing rearward about the cross bar 23 as a fulcrum.

In dumping the chip contents from the conveyer box I, the forward end of the conveyer is raised in any suitable manner, as by a power cable 40 in hooked engagement therewith, and the chips are discharged by gravity from the rear end of the box, the gate 8 having first been raised by manipulation of the lever 33 to permit its lower end to swing free from the box. This dumping action is facilitated by backing the conveyer against a stop member 4i, or other member about which the conveyer may fulcrum in its raising movement, as shown in Fig. 5. The stop member 4! may comprise a length of pipe mounted on the floor at the edge of a pit into which the chips are to be dumped, as shown in Fig. 5. To facilitate fulcruming engagement of the conveyer with the stop 4!, the rearwardly extended end of each bracket 2| is preferably shaped at its under side, as at 42, to engage and pivotally turn on the stop member.

The bottom of the conveyer box i preferably has a slight drop from its rear end forwardly, so that oil on the floor I! and bottom I I] will have a tendency to flow to the forward end thereof. A drain cook 45 is provided at the rear end of the chamber 12 at one side thereof, and this is adapted to be releasably connected to a drainage hose 45, preferably at the point where the conveyer is to be dumped of its chip contents, inasmuch as the raising of the forward end of the conveyer for the purpose of dumping the chips also causes the oil to drain from the rear end of the chamber l2. The stationary part M of the floor provides a pocket in the rear end of the chamber 12 into which the oil may flow when the box is tipped for draining.

In the use of my conveyer, it may be moved about a plant to convenient places for receiving chips which may be wheeled therein over the inclined runway formed by the lower gate 8 and then dumped. When the conveyer has been filled, it may be wheeled to a dumping point where it is backed up against the stop 4| and its forward end then raised to cause the conveyer to fulcrum about such stop and to dump the chip contents into the associated pit, the gate 8 having been raised and released from the notches 2| for such purpose, and the drainage hose 46 may be connected to the drain cock 45 to permit oil in the chamber l2 to be transferred to a desired storage receptacle.

It will be understood that my invention is not limited to any specific construction, arrangement or form of the parts, as it is capable of numerous modifications and changes without departing from. the spirit of the claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent, is:

1. In a device of the class described, a portable box having an end opening, a closure member for said opening having upper and lower pivots, a vertically notched support at the lower portion of said opening for said lower pivots and a vertically notched support near the upper portion of the opening for said upper pivots, said upper support normally standing in position to retain the upper pivot in engagement therewith and to permit the lower pivots to rest in the notches of the lower support, said upper support being movable from normal position to disengage said upper pivots and permit an outward swinging of the closure member on the lower support, and alsobeing movable from normal position to raise the closure to disengage the lower support and permit said member to swing outward on the upper support.

2. In a device of the class described, a portable box having an end opening, a closure member for said opening having upper and lower sets of pivots, upwardly notched supporting means on said box for said lower set of pivots, a pair of arms pivoted to the box sides adjacent the upper portion of the opening and projecting rearwardly from their pivots and having the upper sides of their free end portions notched to receive and support said upper set of pivots, said arms having a normal position and adapted when in such position to interengage the upper set of pivots and permit engagement of the lower set of pivots with said lower support means, and means connected to said arms and operable to move the arms downward from normal position to release the upper set of pivots and upward from normal position to raise the closure member and release the lower set of pivots from their upper support.
